How does 24-hour to 12-hour conversion work?
Hours 00-11 become AM (with 00 rewritten as 12 AM), and hours 12-23 become PM (with 12 staying 12 PM and 13-23 subtracting 12). Minutes and seconds never change – only the hour is transformed.
What is 00:00 in 12-hour format?
00:00 is 12:00 AM – midnight. In 24-hour notation the day starts at hour zero; 12-hour notation labels that same moment as 12 AM.
What is 13:00 in standard time?
13:00 is 1:00 PM. Any 24-hour time from 13:00 through 23:00 subtracts 12 from the hour and labels it PM.
Why convert military time to standard time?

Can I convert times that include seconds?
Yes. Tick the “Include seconds” toggle, pick a time with its seconds column (the picker auto-exposes one), and the output switches to H:MM:SS AM/PM, for example 14:30:45 → 2:30:45 PM.
